Peach tree named Weiser

ABSTRACT

A new and distinct variety of peach tree, named ‘Weiser’, originated as a limb sport on a ‘Bellaire’ tree. It is a midseason variety maturing five days after Loring and seven to 10 days after ‘Bellaire’. The fruit has an attractive bright yellow-flesh, and is freestone, large sized, and flavorful. The surface of the fruit is uniformly attractive orange-red over a yellow background.

Latin name genes and species—Prunus persica.

Variety name: Weiser.

BACKGROUND OF THE DISCLOSURE

This invention relates to peach trees and, more specifically, to a peachtree referred to as a variety of Prunus persica Batsch.

I discovered this new and unique variety of peach tree as a limbmutation on a ‘Bellaire’ tree (not patented) in a cultivated area nearYork Springs, Pa. The tree of this invention produces a fruit ofattractive commercial value, ripening a week to 10 days after ‘Bellaire’and five days after ‘Loring’ (not patented).

This new variety of peach was asexually reproduced by graftingrootstock—‘Lovell’ (not patented) near Aspers, Pa. and such reproductionhas shown this new variety to come true in two successive generations.This propagation of the new variety by grafting under standardcontrolled conditions clearly discloses the continued maintenance of thecharacteristics described herein which distinguish this new variety fromthe parent variety and other related varieties of peach trees.

SUMMARY OF THE INVENTION

The new and distinctive variety of peach tree produces a yellow-fleshed,freestone fruit that is attractively colored, uniformly shaped, large,exceptionally firm and flavorful. It ripens after ‘Bellaire’ and‘Loring’, during an advantageous harvest window for the Mid-Atlanticfruit-growing region. The fruit has a red blush that is more attractivethan ‘Loring’ and covers a greater portion of the fruit surface than‘Bellaire’. The tree is vigorous, drought tolerant and has a regularbearing habit.
